Product Designer (UI/UX)

Hey there - we’re Kinship. We make software for architects and engineering teams. The work they do is genuinely complex - huge libraries of project content, mountains of data, fiddly technical detail - and most of the tools in their world are clunky and joyless. Ours aren’t: our whole reason for existing is to take that complexity and make it feel clean, fast, and a pleasure to use.

That’s the design challenge, and it’s a great one. We’re looking for a product designer who lives and breathes UI - someone who turns dense, complicated workflows into interfaces that feel clean, obvious, and quietly delightful. This isn’t about making pretty pictures; it’s about understanding how people actually work, shaping the right solution, and documenting it with real care. You don’t need to know a thing about architecture or engineering to start - we’ll bring you up to speed on what matters; what counts is that you’re brilliant at making complex software feel simple.

And here’s the best part: we already have a great designer (no joke). So you won’t be a lone designer holding everything together - you’d be joining to help us grow the design team, raise the bar together, and shape how design works at Kinship as we scale. If you’re properly fluent in Figma - the kind of person who treats a well-built component library and a clean handoff as a craft in itself - you’ll feel right at home.

In This Role, You Will

• Own the design of features end to end - from the problem and the flows through to pixel-perfect, developer-ready UI.
• Turn complex, data-heavy workflows into interfaces that feel simple, fast, and genuinely helpful.
• Build and evolve our design system in Figma - components, variants, tokens, and patterns that keep the product consistent as it grows.
• Document your work properly - states, edge cases, and interactions all spelled out - so building it is the easy part.
• Prototype interactions to pressure-test motion and behaviour before anyone writes code.
• Work hand in hand with our engineers, and help grow and shape the design team as we scale.

• 5+ years designing software products - real applications with structured data and rich interactions - not just websites or marketing pages - with a portfolio that shows shipped work, systems thinking, and obsessive attention to detail.
• Mastery of Figma as both a design and a documentation tool. Components, variants, auto-layout, variables/tokens, named states - and handoff that’s clean, complete, and easy to build from. (If your home is Sketch instead, that’s welcome too - it’s the next best thing.)
• Figma files you can walk us through. We care as much about how you document and hand off as we do about the final screens - so expect to show us the inside of a file, not just the pretty frames.
• A deep eye for the details that make an interface just work: typography, spacing, hierarchy, and the unglamorous states - empty, loading, error, edge cases.
• Experience collaborating closely with engineers in a product team - clear communication, thoughtful handoff, and the patience to iterate until it’s right., * Comfort with Framer (or similar) for higher-fidelity interaction prototypes - to show how something should move, not to hand off.
• Comfort reading and tweaking HTML & CSS - enough to understand how your designs become real interfaces, and to nudge things in the browser when it helps. You absolutely don’t need to be a coder, and we won’t screen anyone out for not being one. But if you’re a designer who genuinely loves dipping into code, you’ll have a brilliant time here.
• Experience building or owning a design system.

• Competitive salary.
• A beautiful, plant-filled office in central London (by Southwark tube station) and good coffee (obviously).
• Office-first, with trust-based flexibility.
• A company that believes in work-life balance - we work hard, but go home on time.
• A no-BS team of people who love building great software together - with real autonomy and influence over the product and our culture.

We believe the best people come from all sorts of backgrounds and walks of life. #J-18808-Ljbffr

That’s why Figma is home base: it’s the best tool we know for documenting design, and we lean on it properly - components, variants, auto-layout, variables, named states. (Sketch is the next best thing, if that’s your world.) Tools like Framer are brilliant for what they’re brilliant at - pressure-testing an interaction or showing how something should move - but a prototype is for exploring, not for handing off to the dev team.

We’re looking for someone who treats documentation as part of the craft, not a chore tacked on at the end. Get that right and everything downstream - build quality, speed, the feel of the final product - gets better.

You’re probably someone who

• Is happiest turning messy complexity into something that feels obvious.
• Sweats the details - states, spacing, edge cases - because you know they are the product.
• Likes being in the room where product decisions get made.
• Enjoys shipping quickly and often, in person, with a small, motivated team.
• Values clarity and simplicity over flashy gimmicks.
• Takes real pride in the craft, and in handing work over the way you’d want it handed to you.
